6. 6-Star Wanted Level
Of course, cheat codes don't always have to be about making life a lot easier for the player and the character they are controlling. Sometimes, we can use cheats to make things a heck of a lot more difficult for ourselves and to test our abilities in certain situations, such as trying to escape a six-star wanted level. There's nothing quite like going from no police attention at all straight to a NOOSE helicopter chasing you down to really test your nerves in the GTA series and this code is one of our personal favourites. Seeing how long you can withstand a six-star wanted level in Grand Theft Auto is a tried-and-tested pastime and can lead to hours upon hours of fun.
